What does how mean?
“How” is an interrogative and exclamatory adverb used to ask about manner, means, degree, or condition. It commonly appears in direct questions such as “How do you know?” and in indirect questions such as “I wonder how they solved the problem.” The word can also introduce a polite request for information or instruction: “Let me know how to proceed.” In exclamations, “how” expresses surprise, admiration, sympathy, or strong feeling: “How strange that no one noticed!” Its use in greetings, including “How are you?” and the formal “How do you do?”, is especially familiar in British and American English. The flexibility of “how” makes it central to everyday conversation, although the related “what” is preferred when asking about the identity or nature of something.

“How” is one of the most useful question words: it can ask about methods, measure degree, or turn a simple observation into an exclamation.

Where does how come from?
The word descends from Old English hū, an interrogative adverb and adjective meaning “in what way” or “by what means.” It continues the Proto-Germanic interrogative *hwō, related to forms such as English “who,” “whom,” and “whose.” Modern “how” developed many of its grammatical uses from these older interrogative and exclamative functions.
